We present a new generic construction of a public-key encryption (PKE) scheme secure against leakage-resilient chosen-ciphertext attacks (LR-CCA), from any Hash Proof System (HPS) and any one-time lossy filter (OT-LF). Efficient constructions of HPSs and OT-LFs from the DDH and DCR assumptions suggest that our construction is a practical approach to LR-CCA(More)
Clinical decision support system, which uses advanced data mining techniques to help clinician make proper decisions, has received considerable attention recently. The advantages of clinical decision support system include not only improving diagnosis accuracy but also reducing diagnosis time. Specifically, with large amounts of clinical data generated(More)
Attribute-based encryption (ABE) with outsourced decryption not only enables fine-grained sharing of encrypted data, but also overcomes the efficiency drawback (in terms of ciphertext size and decryption cost) of the standard ABE schemes. In particular, an ABE scheme with outsourced decryption allows a third party (e.g., a cloud server) to transform an ABE(More)
In Eurocrypt 2010, Fehr et al. proposed the first sender equivocable encryption scheme secure against chosen-ciphertext attack (NC-CCA) and proved that NC-CCA security implies security against selective opening chosen-ciphertext attack (SO-CCA). The NC-CCA security proof of the scheme relies on security against substitution attack of a new primitive, "(More)
Related-Key Attacks (RKAs) allow an adversary to observe the outcomes of a cryptographic primitive under not only its original secret key e.g., s, but also a sequence of modified keys φ(s), where φ is specified by the adversary from a class Φ of so-called Related-Key Derivation (RKD) functions. This paper extends the notion of non-malleable Key Derivation(More)
OBJECTIVE Previous studies have evaluated the associations of TNF-α, IL-10 gene polymorphisms and susceptibility to pSS, but the results remained controversial. To assess the associations between TNF-α-308, IL-10-1082, -819, -592 polymorphisms and pSS risk, a meta-analysis was conducted. METHOD The available articles were searched in PubMed, EMBASE and(More)
INTRODUCTION The evidence from published studies on the association between obesity and rheumatoid arthritis has been contradictory. To clarify the association between obesity and rheumatoid arthritis, we conducted a systematic review and dose-response meta-analysis to assess the relationship between body mass index and rheumatoid arthritis risk. METHODS(More)
BACKGROUND Several polymorphisms in the apolipoprotein C3 (APOC3) gene have been found association with hypertriglyceridemia(HTG), but the link with coronary heart disease(CHD) risk between ethnicities was still controversial. Among them, reseachers paid more attentions to the promoter polymorphisms T-455C and C-482T because both of them located in(More)
At CCS 2003, Blomer, Otto, and Seifert proposed a new CRT-RSA signature algorithm, which was claimed to be secure against hardware fault attack. Unfortunately, one year later, Wagner presented a simple and practical fault attack on the so-called BOS algorithm. In this paper, we give a further cryptanalysis of the BOS algorithm and can completely break the(More)
